I have configured the Bluecherry DVR for 1-hour recording segments. The camera is configured for 30 fps. Audio is enabled in both. The generated .mkv file has video as 60 fps instead of 30. The video stream in the file is 1 hour, 7 minutes 39 seconds (instead of the expected 1 hour), yet the audio stream is exactly 1 hour. Playback of the .mkv file gives video that runs too fast, and I've been unable to deduce a way to sync the video and audio.

I have tried to resample the video with: ffmpeg -i 20-00-04.mkv -r 30 output.mpg which gives me video that runs at the correct speed, but doesn't help with syncing the audio. (That command may resample the audio too, which would be unuseful; I'm not sure.)

Here's the info on the video file. I'd greatly appreciate help producing a video that plays at the correct speed and is synced with its audio. Thanks in advance!
